Abstract

According to one embodiment, a memory system includes a nonvolatile semiconductor memory device, controller, memory, wireless communication function section, and extension register. The controller controls the nonvolatile semiconductor memory device. The memory is serving as a work area of the controller. The wireless communication module has a wireless communication function. The extension register is provided in the memory. The controller processes a first command to read data from the extension register, and a second command to write data to the extension register. The extension register records, an information specifying the type of the wireless communication function in a specific page, and an address information indicating a region on the extension register to which the wireless communication function is assigned.

Claims26

Dependent claims

A wireless LAN card being connectable to a host device, the card having one or more extended functions including a first function, the card comprising:

a NAND memory which stores data;
a controller which controls the NAND memory in response to a request from the host device;
a wireless communication module for communicating with outside of the card;
and
an extension register which includes a plurality of pages,
wherein the controller processes a first command to read data from the extension register in a unit of a page, and a second command to write data to the extension register in a unit of a page,
wherein a specific page of the extension register stores information indicating a number of the one or more extended functions,
wherein the extension register includes a first address region to which the first function is assigned,
wherein the first address region stores:
first information to find a driver of the host device which can be used to control the first function;
and
second information indicating a second address region of the extension register to which the first function is assigned,
wherein the first address region and the second address region are located at different pages of the extension register, and
wherein the second address region includes:
a first data port for writing a third command to perform the first function;
and
a second data port for reading a response data of the third command.
